FOLDING BEDSTEAD.

SPECIFICATION forming part of Letters Patent No. 719,292, dated January 27, 1903. Appnmion nea August so, 1902. Serin No. 121,661. (No man.)

To all whom t may concern:

Be it known that I, ARMAND ALLENDY, a citizen of the French Republic, residing at 2l Avenue de Messine, Paris, France, have invented certain new and useful Improvements in Folding Bedsteads, of which the following is a specification.

My invention relates to folding bedsteads, the main object being to provide a bedstead which can be folded and unfolded with a minimum of exertion, a particular feature being an arrangement for automatically tilting the main frame or bed-bottom, which is preferably constituted by a spring-mattress secured to a frame, the connection with the head and foot supports being such that the raising of the main frame or bed-bottom (for brevity I will refer to it as the spring-mattress) is not done by lifting its foot end, but by lowering the foot end and pushing, after the manner of pushing a barrow or handtruck, so that only a very small effort is required in folding the bedstead, and in order that my invention may be clearly underderstood I shall describe the same with reference to the accompanying drawings, of which- Figure l shows a longitudinal section of the bed in the open position. Fig. 2 shows a side elevation of the bed in its folded position. Fig. 3 is a detail sectional view illustrating the buffers t fastened to the mattresssupport.

In the open position, Fig. l, the springmattress ct rests upon projections from the head-support b and the foot-support c, both such supports being preferably mounted on ball or other casters. The head-support b may be fixed to a wall or only leaned against the same. The foot-support cis movable, so that it can run on the floor. There are brackets d e on the head and foot supports, respectively, for the ends of the spring-mattress to rest upon. On each side of the spring-mattress are jointed the upper ends of bent leversf at points o in a line passing nearly but not quite through the center of gravity, so that there may be a slight preponderance of weight at the foot end. The lower ends lower part g of the foot-supports c. The said bent levers f are connected together by stays h, so as to form a support to receive the spring-mattress when it is tilted on its centers o.

In the vertical lines passing through the centers o, to which the upper ends of the bent levers are connected and pivoted at o', one at each side, is a second pair of levers lc, preferably connected together by stays j, and forming,with the bent levers f, a compass-like arrangement. The other ends of this second pair of levers k are centered to the lower end t' of the head-support b, each of the said levers k being also connected to the head-support b by a slotted link Z to limit the inclination of the said levers of the second set relatively to the head-support when the bedstead is unfolded.

The ordinary mattress m may rest on a covering of wire-gauze fn, stretched over the spring-mattress and turned upward at both ends. The head end of this wire-gauze covering may be kept raised by a special frame p or struts or the like when the bedstead is unfolded. The foot end of the spring-mattress can be connected to the foot-support c by'any suitable means-duch, for example, as a bolt q.

Cross-pieces r s insure the rigidity of the springmattress and allow of chests being formed at each end for the reception of pillows, holsters, sheets, quilts, and the like.

To raise the bedstead, the wire-gauze covering n is lowered after the two chests being filled and the head of the ordinary mattress is strapped to the spring-mattress. The bolt q is then withdrawn and the operator draws the upper part of the foot-support toward him, so that it tilts on its feet or casters and assumes an outwardly-inclined position c', Fig. 1. Owing to the preponderance of the weight of the spring-mattress being slightly at its foot end and to the pull exerted at the points g, at which the bent levers are attached to the foot-support, the spring-mattress will turn on the points 0 o near its center of gravity, to which the upper ends of the levers are connected and the lower end of the spring-mattress will descend onto the support formed by the stays h of the bent levers, the head end of the said spring-mattress ris- IOO ing and leaving the head-support, so that the mattress assumes an inclined position ct with its foot end lowermost, as shown in dotted lines on Fig. 1.

To lessen the shock of the descent of the foot end of the spring-mattress onto the floor, bufferst may be provided on the mattress-support, as shown in Fig. 3, and if these be of material such as rubber they will prevent the iloor being marked by the spring-mattress while the bed is being closed. On the bottom of the foot-support there may be wedges u, which in the closed position will somewhat penetrate the iioor and prevent the springmattress from coming forward. The headsupport may, if desired, be fixed to the wall, and the two end supports of the bedstead may be connected together by any suitable device. When the foot-support c is pushed toward the wall or head support inclosing the bedstead, the parts are folded by a movement like that of pushing a barrow or hand-truck, the two arrangements of levers 7c fclosing like a pair of compasses, and at the end of the movement the parts will lie parallel (or nearly so) with each other, the

spring-mattress and the ordinary mattressl being between the head and foot supports, Fig. 2, and the space occupied by the projection of the folded bedstead will be very small-say about one foot.

Having now particularly described and ascertained the nature of my invention and in what manner it may be performed, I declare that what I claim is y l. In a folding bedstead a spring-mattress ct with two centers o o', a foot-support c, two levers f jointed to the center o and to the foot-support c, a head-support b, two levers 7c jointed to the center 0' and to the headsupport b, stays h between the levers f forming a support to receive the spring-mattress, a slotted link Z between the levers 7c and the head-support to limit the inclination of the said levers anda bolt qconnecting the springmattress to the foot-support when the bed is in its open position, substantially as described and illustrated in the accompanying drawings.

2. In a folding bedstead, having a springmattress pivoted on two centers o d, and levers for joining said centers to the head-supports and foot-supports respectively, means for maintaining the bedstead in open position, consisting of brackets CZ e on the head and foot supports, of a bolt q connecting the foot-support and the mattress, and means for preventing the bedstead from opening itself when folded, consisting of two wedges u in the foot-support arranged so as to penetrate somewhat in the floor, substantially as described and illustrated.

3. In a folding bedstead, the combination with the head and foot boards and mattresssupport, said head and foot boards being provided with projections on which said mattress-support rests, of a plurality of levers extending from the lower portion of the headboard to approximately the longitudinal middle of the mattress-support, and a plurality of levers extending from the lower portion of the footboard4 to approximately the longitudinal middle of said mattresssupport,for the purpose specified.

4. In a folding bedstead, the combination with the head and foot boards and mattresssupport, said head and foot boards being provided wit-h projections on which said mattress-support rests, of means for locking said footboard and said mattress-support together, a pluralityof levers extending from the lower part of said headboard to approximately the longitudinal middle of said mattress-support, and a plurality of levers extending from the lower portion of said footboard to approximately the longitudinal middle of said mattress-support.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- DQSSGS.
